This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1250, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SU63-100 Standard Cylinder SU80X1250
The AirTAC SU63-100 Standard Cylinder SU80X1250 is a double-acting profile-type standard cylinder with a Ø80mm bore and 1250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1250, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1250
The AirTAC SU80X1250 is a discontinued double-acting profile-type cylinder with an 80mm bore and 1250mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, its direct replacement is the SAU80X1250, retaining the same 3/8" port, M20x1.5 rod thread, and SC-series mounting compatibility.
This SKU lacks a magnet and cannot accept a sensor. If sensing is needed, the SAU upgrade uses CMSG/DMSG/EMSG switches, while the SAUF variant adds a built-in valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X1250 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X1250 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU63-100 Standard Cylinder SU80X1250 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets along a 1250mm conveyor section using 2513N of thrust at 0.5MPa, guided externally to prevent rod bending.
Large Assembly Press
Drives a 1250mm tooling carriage to seat heavy industrial components, relying on adjustable 28mm air cushions to decelerate at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1250 with the SAU80X1250
To replace this discontinued SU80X1250, order the SAU80X1250 direct equivalent, verifying your 3/8" port, M20x1.5 thread, and SC-series mounts. Because this 1250mm stroke is long, use external guides to prevent rod bending and side-load damage. This non-magnetic SKU cannot take a switch; the SAU uses CMSG/DMSG/EMSG sensors. For sizing, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. Note that air cushions only decelerate; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1250
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU63-100 Standard Cylinder SU80X1250 FAQ
Yes, the SU80X1250 is discontinued. The direct replacement is the AirTAC SAU80X1250, which matches the 80mm bore, 1250mm stroke, 513kgf max force, 3/8" port, and SC-series mounting.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N at 0.7MPa, and a 513kgf max at 1.0MPa. This specific SKU has no magnet and cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
